Iyunithi yokusulungekisa i-oyile kushishino lwepetrochemical yenzelwe ukusetyenzwa kwe-oyile ekrwada, ukuvelisa iindidi ezahlukeneyo zepetroli, idizili, i-kerosene kunye nezinye i-oyile zamafutha, ii-oyile zokuthambisa kunye nemathiriyeli ekrwada yeekhemikhali.
Iimfuno ezisisiseko zesityalo sokucoca i-oyile kwi-valve: ukuhlangabezana neemfuno zenkqubo, qinisekisa ubomi benkonzo yevalve, kulula ukuyisebenzisa kunye nokugcina, isakhiwo esincinci, esikhuselekileyo kunye nokuqhuma.
1. Iimfuno zokutywinwa
Isitywina se-Stem: Ukupakishwa okusetyenziswe kwi-valve kufuneka kuhlangabezane neemfuno zenkqubo ephakathi kunye nokulungelelanisa ubushushu kunye noxinzelelo lwe-medium.Iibhokisi zokuhlohla iivalve zihlala zivuza ngexesha lokusebenza kweeyunithi ezininzi, ngoko ke iindawo zokucoca ezininzi zithatha indawo yazo zonke iipakethe phambi kokugunyaziswa.
2. Iimfuno zemathiriyeli
Izixhobo zevalve ezisetyenziswa kwizityalo zokucoca ioyile ikakhulu zibandakanya intsimbi yekhabhoni, intsimbi yealloy kunye nentsimbi engenasici.Kuphuhliso lwenkqubo yokusulungekiswa, utshintsho kwiipropathi zeoyile ekrwada, ukusetyenzwa nzulu kwe-oyile ekrwada, kunye nokwanda kobushushu kunye noxinzelelo lweemeko zokusebenza, kukho iimfuno ezintsha zezixhobo zevalve, njengezinto ezinganyangekiyo kwi-SS316. kunye ne-polymeric linings.

3. Iimfuno zokhuseleko
Ishishini lokusulungekisa i-oyile liqheleke kwiingozi ezinokutsha kunye neziqhushumbisi ngexesha lothutho, ngoko ke iimfuno zokhuseleko kwiivalvu zingqongqo, kwaye kufuneka kwenziwe ubungqina bokudubula kunye nokutsha.Umzekelo,iivalvu zebhola zombane ezingaqhushumbayokwayeiivalve zebhabhathane zombane ezingaqhushumbayoinokusetyenziswa kakuhle kule medium.
4. Iimfuno zokuchazwa
Ushishino lokusulungekiswa kweoli lunendima ebalulekileyo kuqoqosho lwelizwe, kwaye iingenelo zezoqoqosho zemizi yokucoca ioli zihlobene ngokusondeleyo nomlinganiselo wazo.Ke ngoko, indawo yokucoca enkulu yindlela yophuhliso lwexesha elizayo.Iinzuzo kukugcina utyalo-mali, ukunciphisa ukusebenza komhlaba, ukunciphisa iindleko, kunye nokunciphisa ukusetyenziswa kwamandla, ngoko ke umkhwa weevalvu ezizenzekelayo ufumana ingqalelo engakumbi nangakumbi.

I-COVNA yethu igxile kwimveliso yeevalvu ezizenzekelayo, kwaye ineminyaka emininzi yamava obunjineli atyebileyo aneminyaka emininzi yamava kwiiprojekthi zobunjineli bepetroleum kunye nokucokisa.

Ukuba uyindawo yokucokisa efuna iivalvu okanye ufuna ukufumana izisombululo zevalve yokucoca, nceda.Qhagamshelana nathi.
